Large Scale Nickel Column Leach
Core was recently engaged to conduct large scale column leach tests on lateritic nickel ore samples. The primary technical objective of the columns tests was to generate pregnant leach solution (PLS) for subsequent Ni recovery testwork. The columns generated 5000 L of PLS, enough for use in bench and pilot scale testing of downstream neutralisation and solvent extraction processes.
The project was fast tracked as suitable 1m diameter columns were readily available from Core’s extensive inventory of equipment. The columns were installed on two large platform scales to monitor mass flow and were run continuously for 8 weeks. Daily readings were taken to monitor the performance of the leach.
The programme is a demonstration of Core’s abilities to work with our clients to achieve the technical requirements of their projects. Key to the success of this column leaching programme were Core’s extensive inventory of equipment, a can do attitude, and technical expertise to generate the leach liquor required from the ore supplied.
